PATENT OFFICE 3 Claims.

This invention relates to spring curtain threaders and has for an objectto provide a device for facilitating the spreading of the hem of acurtain to promote ease of threading the curtain rod through the hem,the device having spring legs which are adapted to enter between theflanges of all sizes of curtain rods 'so that a single device of thischaracter may be used to thread curtain rods of various sizes throughouta dwelling, through the hems of curtains.

A further object is to provide a device of this character which will beformed of a single length of spring wire, which will be inexpensive tomanufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modifications may be resorted to within the scope of theappended claims without' departing from the spirit or sacrificing any ofthe advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a front elevation of a curtain rod equipped with a threaderconstructed in accordance with the invention and showing the applicationof the same to the initial end of a hem of a curtain.

- Figure 2 is a plan view of the parts shown in Figure 1.

Figure 3 is a perspective view of the threader.

Figure 4 is a front elevation of the threader.

Figure 5 is an edge elevation of the threader.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, I0 designates a metalliccurtain rod of the' type having longitudinal flanges. As is well knownmetallic curtain rods of this type are manufactured in a large number ofdifierent widths.

The curtain hem threader ll comprising the subject matter of thisinvention, is formed from a single length of wire bent centrally uponitself to form two convolutions l2 and I3 of a spiral, the ends of thewire then being bent to lie against the sides of the spiral so that theconvolutions diverge from each other, as best shown in Figure 5. Theends of the wire 14 are then directed substantially paralel to each.other and in the same plane and are provided near their extremities withoiisets or substantially V-shaped bends IS the apexes of which areturned oppositely to each other, as shown in Figure 3, so that theextremities will converge toward each other and thus be easilyinsertable in a curtain rod of any width.

The threader is applied to the curtain rod by thrusting the extremitiesof the ends l4 inside of the longitudinal flanges of the curtain rod and5 then forcing the same longitudinally of the curtain rod by pressureupon the convolutions I2 and i3. The spring ends l4 tend to hold theV-shaped bends I5 in tight frictional engage ment with the innersurfaces of the curtain rod 10 flanges so that the convolutions l2 andI3 may be inserted in the hem 16 of a curtain H whereupon theconvolutions will spread the hem laterally as the threader is movedthrough the hem by pressure upon the curtain rod so that the curtain 15rod will be easily and quickly threaded into the hem.

From the above description it is thought that the construction andoperation of the invention will be fully understood without furtherexplana- 20 tionl What is claimed is:

1. A curtain rod threader comprising a spring wire deformed to providediverging convolutions of a spiral adapted to enter and spread laterallythe hem of the curtain, the ends of the wire being directed from thespiral to lie in the same plane and being provided near the extremitieswith bends forming jaws adapted to frictionally engage the flanges of ametal curtain rod and 30 anchor the threader to the rod.

. Ward each other.

3. The combination with a metal curtain rod having longitudinal side.flanges, of a curtain hem threader comprising a single length of springwire bent centrally upon itself to form two diverging convolutions of aspiral adapted to spread laterally the hem of a curtain, the ends of thewire being bent to lie in the same plane and being provided withsubstantially V-shaped bends the apices of Which are turned outwardly sothat the ends of the wire converge toward each other, said extreme endsbeing adapted to guide the threader beneath the flanges of the curtainrod', said V-shaped bends frictionally engaging the inner surfaces ofthe flanges and yieldably attaching the threader to the curtain rod.
